EAzoE STROPPER Application fil ed April 12,

This invention relates to an improved razor stropper of the'type used for stropping safety razor blades; and it has for its main object the production of a stropper in which a blade to be stropped is moved into stropping position by a movement of an actuating handle for the device and then by acontlnuing movement is moved along the strop. to effect the stropping operation With this and other objects not specifically mentioned in view, the

stropper constructed in accordance with the P invention; Fig. 2 is a sectional view on an,

enlarged scale of apart of the device shown in Fig. 1 and showing the manner ofpresentation of one side oi an edge of aiblade' to the strop during the movement indicated by the arrow; Fig. 3 is, a similar'vi'ew' showing the manner ofpresentation ofthe other side of an edge of a blade'to the strop ,duringthe opposite movement indicated by the arrow; Fig. 4 is a plan view of the device shown inFig. l; andFig. 5 is a sectional view taken on the line 55 in Fig. 4:.

In carrying the invention into efiect, there is provided a razor strop of a well known type and which maybe provided with a hook at one, end and a loop at the other in the usual manner, a frame mounted on said strop and adapted to! be moved along-saidstrop, a blade holder mounted in said frame and adapted to move independently of-and concurrently with the frame during different parts ofthe stropping operation, a handle for actuating the device, and operatingconnections-between said holder andsaid handle whereby movement of said handle in either direction first moves a blade into stropping position and then moves it along said strop. These parts may be considerably Varied in construction within the scope'of the claims, for the specific structure selected to illustrate the invention is but one of numerous.

structure shown and described.

Referring to the drawings, 6 indicates side plates or" a frame adapted, to be moved along y a'ra'z'or strep 7 and supported thereby. There are two of these side plates and they are connected by pins 8 each of which carries 7 The rollers 9 are unsymmetrically' arranged in the frame to cause the opposite sides of an edge of a curved blade to be presented to the strop Tat the proper different angles; although .this arrangement is not required in case of a flat blade. Thus the frame is mounted on the strop. o

To supporta blade to be stropped,vthere is provideda blade holder which is mounted in the fraine m ounted on the strop. This blade holder c'omprisesya bar '10 carried by two levers 11-11, both of which are fulcrumed' on one or" the pins 8, e. on thepin nearestthe middle of the frame including the Plates 6-6.

To clamp ablade to be stropped on the bar 10,- the? latter is provided with two lugs The invention, therefore, is not to be restricted to the precise d'etailsof the;

12-12 struck up from the bodyyof the bar and projecting through apertures 1313'in" a'blade'B. The bar 10 is turthenprovided with a Stud 14 whichpasses through a cen-.

tral aperture in'a blade and carries a clamping nut 15 otwell Known'construction and position inwhich they lie when the handle is being moved tothe. left, whilelin 2 they are shown in the position in which they lie when the handle is being moved to the right. Assuming that the strop 7 isheld taut" and the parts are in the position shown in- Fig. 1,. and that the end of. a movement -to the lefthas about been reached. The oper ator thenreverses the movement of the handle 17' and moves it'towar'd the right or toward the dotted position shown. This-part of the movement to the right swings the blade from the position shown in full lines to the posltion shown in dotted lines, thus presentmg the other side of the same edge of the blade tothe strop. Continuation of the handle movement to the right moves the frame along the strop and effects the stropping action on the blade edge. At the end of the strop arranged to form in said strop two stropping sections of different angularity with respect to the main body portion of the strop, a blade holder swingable in saidframe for movement to either one oftwo positions in which a held blade engages said sections at different stropping angles, a handle, and connections between said handle and said holder in which the latter is fixed operating in either direction to first move the holder into one or the otherof said stropping positions and then move said frame along said strop.

2. The combination with a razor strop, of

a frame movably mounted on said strop and having offset means on opposite sides of aid strop arranged to form in said strop two stropping sections of different angularity the latter fixed operating in either direction with respect to the main body portion of the strop, a blade holder swingable in said frame for movement to either one of two positions in which a held blade engages said sections at different stropping angles, a handle, and connections between said handle and said holder operating in either direction to first move the holder into one or the other of said stropping posltions and then move said frame along said strop, saidframe including two side plates spaced apart and connected by pins fined therein supporting said offset means.

3. Th combination with a razor strop, of a frame movably mounted on said strop and having offset means onopposite sides of said strop arranged to form in said strop two stropping sections of different angularity with respect to the main body portion of the strop, a blade holder swingable in said frame for movement to either one of two positions in which a held'blade engages said sections at different stropping angles, a handle, and connections between said handle and said holder operating in either direction to first move the holder into one or the other of said stropping positions and then move said frame along said strop, said frame including two side plates spaced apart and connected by two pins fxed therein below the strop and two unsymmetrically arranged pins fixed therein above the strop carrying rollers forming said offset means.

l. The combination with a razor strop, of a frame movably mounted on said strop and having ofi'set means on opposite sides of said strop arranged to form in said strop two stropping sections of different angularity with respect to the main body portion of the strop, a blade holder swingable in said frame for movement to either one of two positions in which a held blade engages said sections at different stropping angles, a handle, and connections between said handle and holder operating in either direction to first move the holder into one or the other of said stropping positions and then move said frame along said strop, said frame including two side plates spaced apart and connected by pins lined therein one of which supports said connections.

The combination with a razor strop, of a frame movably mounted on said strop and having offset means onopposite sides of said p arranged to form in said strop two *pping sections of diiferent angularity with respect to the main body portion of the str p, a blade holder swingable insaid frame for movement to either one of two positions in which a held blade engages said sections at different stropping angles, a handl and connections between said handle and said holder operating in either direction to first move theholder into one or the other of said stropping positions and then move said frame along said strop, said holder including a blade supporting bar having lac e positioning lugs and blade clamping means.

, 6. The combination witha razor strop, of aframe movably mounted on said strop and having offset means on opposite sides of said strop arranged to form in said strop two stropping sections of diiferent angularity, a blade holder movable in said frame to cause a held blade to alternately engage said sections, a ia-ndle, and connections between said handle and said holder whereby movement of the former in either direction first moves the holder into, stropping position and then moves said framealong said strop, said connections including spaced levers pivotally connected with said frame and with said handle and rigidly connected with said holder.

In testimony whereof, I have signed my name to this specification.
